147f7386da Disable the AppOp Restriction for IpSec Tunnels
This CL temporarily removes the AppOp restriction
that disallows creation of IpSec tunnels due to
the lack of the appropriate AppOp in AOSP/master.
When the relevant framework merges out to master,
this CL should be reverted.

d21e909fd3 Rework Exception Handling for IpSecManager
In order to properly support EOPNOTSUPP this CL
applies a consistent approach to handling Exceptions.
Hereafter, all exceptions that aren't of a special
method-specific type (such as SpiUnavailableException)
will all be returned to the calling process unchanged.
At the API call site, the ServiceSpecificException,
which is really an Errno, will be inspected and either
converted to an unchecked exception for types we know,
or it will be converted to an IOException in cases where
that method can return a checked exception. In cases
where we do not expect an errno, we will simply throw
a generic RuntimeException. This means all API calls
will now properly throw UnsupportedOperationException
and may be CTS tested accordingly.

b25e678b4b Update IpSecManager to use InetAddress and prefixLen
LinkAddress constructors are currently @hide; this change updates
IpSecManager to use InetAddress and prefixLen, and then construct a
LinkAddress internally. LinkAddress is used over the binder interface to
IpSecService to ensure validity.

cac8775b2a Add AppOps Checks for MANAGE_IPSEC_TUNNELS

a context so change the service mode to a cached

2cb46550f7 Check for bpf support at NetworkStatsService start
The current implementation check for bpf map existance whenever a
NetworkStats request comes in. The check is not efficient and may
require additional permission for threads. So a member variable is added
to NetworkStatsService to store the bpf configuration status and is
initialized when NetworkStatsService start.

1f37112a51 Remove the unused file parsing function
With the new xt_bpf support for iface stats. We no longer need to parse
the per interface stats from /proc/net/dev. And since the old xt_qtaguid
code path also not depend on it, we can completly remove that helper
function since no caller is depending on it now.

This change forces Socket and DatagramSocket to populate the
SocketImpl, ensuring that the socket file descriptor can be
retrieved when applying Transport mode Transforms

This is done by calling getSoLinger(), triggering a getImpl(), which
triggers setImpl() if needed.

feebc885a2 Check mOwnedByTransform to avoid DELSA on SPI
The owned by transform flag prevents the removal
of an SPI from accidentally deleting an associated
SA in the kernel. That flag wasn't actually being
checked, so deleting an SPI would result in the
transform being removed.

The existing code already guarantees that the SA is
deleted when the transform is deleted

8f5d138277 Minor cleanups to NetworkStats interface tracking.
Currently, when a network goes into CONNECTED state, we call
updateLinkProperties and then notifyIfacesChangedForNetworkStats.
The latter is unnecessary, as there are exactly two cases:

1. networkAgent.linkProperties != null: updateLinkProperties will
   call notifyIfacesChangedForNetworkStats, because oldLp is null
   and networkAgent.linkProperties is not null.
2. networkAgent.linkProperties is null: there is no need to call
   notifyIfacesChangedForNetworkStats, because no interfaces were
   added or removed. When they are, updateLinkProperties will be
   called again.

Removing the call to notifyIfacesChangedForNetworkStats avoids
a stats poll, which is a minor performance improvement.

Also, remove the NetworkStatsService code to do asynchronous
interface updates, since it has no callers.

905f034c57 Return non-negetive value in getMobileStats method
The current implementation of getMobileRxBytes and all the similiar
method adds up the return values for multiple calls to getRxBytes so if
all of them return UNSUPPORTED for any reason, getMobileRxBytes() would
return a value such as -3. This behavior is not compliance with the cts
TrafficStatsTest which always assume getMobileRxBytes to return a
non-negetive value. The method now will check tha stats get from
getRxBytes method and add them up only if the stats is valid.

b559164017 Move Keepalive out of IpSecTransform.Builder
The lifecycle of Keepalive offloading is, unfortunately
different from that of an IpSecTransform. Because starting
a keepalive is fundamentally asynchronous, and isn't valid
until after a transform exists, it will now be a separate
optional procedure that may succeed or fail. It remains
linked with a Transform by the need for a Transform to exist
in order to initiate a Keepalive.
